  1. 1. Test Charge Response of a Dusty Plasma with Grain Size Distribution and Charging Dynamics

    Författare :Muhammad Shafiq; Michael A. Raadu; Jens Juul Rasmussen; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Dusty plasmas; Complex plasmas; Grain size distribution; Grain charging dynamics; Lorentzian distribution; Kappa distribution; Test charge response; Delayed shielding; Energy loss; Drag force; Wake field.; Plasma physics; Plasmafysik;

    Sammanfattning : This doctoral thesis reports analytical and numerical results for the electrostatic response of a dusty plasma to a moving test charge. Two important physical aspects of dusty plasmas, namely grain size distribution and grain charging dynamics were taken into account. LÄS MER

    Sammanfattning : This thesis is about firm dynamics, and relates to the size and growth-rate distribution of firms. As such, it consists of an introductory and four separate chapters. LÄS MER

  4. 3. Heuristic Mathematical Programming Methods for Lot-sizing, Inventory Control, and Distribution Cost Estimation in the Supply Chain

    Författare :Björn Samuelsson; Athanasios Migdalas; Anders Segerstedt; Sven Axsäter; Leonidas Pitsoulis; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic lot size; Multi-echelon inventory systems; Supply network optimization; Distribution; Location analysis; Distribution cost approximation; Industrial Logistics; Industriell logistik;

    Sammanfattning : The supply function has an important role to support the business to create a customer value. Two important parts of this process is to have the warehouses and production sites in the right location and to have the right items stocked at the right level. This thesis is concerned with those two parts of the supply chain management.

  5. 4. Development and Applications of Detailed Kinetic Models for the Soot Particle Size Distribution Function

    Författare :Karl Netzell; Förbränningsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysik; flamelet model; Physics; particle distribution; soot; moment method; sectional method; particle size distribution function;

    Sammanfattning : Two different mathematical methods of implementing a detailed kinetic soot model have been employed in this work. The theoretical description of the soot modeling employed in this work is divided into three parts. Initially a detailed kinetic soot model is described from a chemistry and physics perspective.

  7. 5. Opportunistic Content Distribution : A System Design Approach

    Författare :Sylvia Todorova Kouyoumdjieva; Gunnar Karlsson; Martin May; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The penetration of smart pocket-size devices that provide constant Internet connectivity, such as mobile phones, has significantly changed the way people obtain, view and share information. Content provision is not anymore a prerogative to professionals; individuals are not solely customers, but also act as content generators and distributors. LÄS MER
